In Heron's formula , area of triangle =sqrt(s(s-a)(s-b)(s-c)), s is …………………..of the triangle.

The diagonal of a rectangle is 10 units. The formula to find the diagonal is d=sqrt(l^(2)+b^(2)) . Where l and b are length and breadth respectively. (10+b)(10-b) is equal to______.

In any triangles ABC, establish Napier’s formula, tan((B-C)/2)=(b-c)/(b+c)cot(A/2)

If the time period t of the oscillation of a drop of liquid of density d, radius r, vibrating under surface tension s is given by the formula t=sqrt(r^(2b)s^(c)d^(a//2)) . It is observed that the time period is directly proportional to sqrt((d)/(s)) . The value of b should therefore be :

If the time period t of the oscillation of a drop of liquid of density d, radius r, vibrating under surface tension s is given by the formula t=sqrt(t^(2b)s^(c)d^(a//2)) . It is observed that the time period is directly proportional to sqrt((d)/(s)). The value of b should therefore be:
